How does the operating cost of the MBR membrane sewage treatment process compare with the traditional process?

　　The operating cost of the MBR membrane sewage treatment process is higher than that of the traditional process:

　　Direct operating costs:

　　MBR process: 0.5-0.9 yuan/m³

　　Traditional process: average about 0.62 yuan/m³

　　MBR is about 0.15 yuan/m³ higher than traditional process

　　Considering equipment depreciation:

　　MBR process is nearly 0.4 yuan/m³ higher than that of the traditional process

　　Specific comparison (three sewage treatment plants of similar scale in the same region and period):

　　Without considering the cost of membrane/filter cloth replacement:

　　MBR is about 0.138 yuan/m³ higher than secondary biological treatment + submerged filter cloth filter

　　MBR is about 0.046 yuan/m³ higher than secondary biological treatment + submerged ultrafiltration

　　When considering the cost of membrane/filter cloth replacement:

　　MBR is about 0.352 yuan/m³ higher than secondary biological treatment + submerged filter cloth filter

　　MBR is about 0.156 yuan/m³ higher than secondary biological treatment + submerged ultrafiltration

　　Main cost structure:

　　Electricity fee: about 0.3-0.5 yuan/m³

　　Equipment depreciation: about 0.15-0.30 yuan/m³

　　Others: chemical fee, labor fee, sludge treatment and disposal fee, etc.

　　In general, the high operating cost of the MBR process is one of its main disadvantages. The future development direction of the MBR process will focus on energy saving, consumption reduction and operating cost optimization, including improving membrane materials, reducing membrane material costs, optimizing membrane component structure and aeration methods, etc.
